To minimize deadweight losses, tax rates should vary unpredictably so agents cannot rearrange their work and consumption habits. As a result, optimally set tax rates will be a nonstationary time series or, put differently, changes in the tax rate will be unpredictable. This paper identifies...

Until recently, the trend in world capital markets has been toward increasing globalization. Recent events in Latin America and Asia have caused many in policy-making circles to question whether this trend should be wholly, or at least partially, reversed. It is commonly argued that?at a...

Strategic interjurisdictional behavior and the interaction over time of the mean and dispersion of average tax rates across states are analyzed in a vector autoregression model. Variance decompositions reveal that fiscal competition explains roughly one-third of the time variation of state and...

This paper analyses the effects of non-tariff barriers, in terms of both variable and fixed export costs, on trade structure. The relationship between fixed and variable trade costs determines whether international trade emerges. If trade emerges, only variable, but not fixed export costs,...

We consider the standard spectral estimators based on a sample from a class of strictly stationary nonlinear processes which include, in particular, the bilinear and Volterra processes. It is shown that these estimators, under certain mild regularity conditions are both consistent and...

This research study examines the behavior of currency rate, long memory features, and longterm stability in the returns of thirteen Asia-Pacific currencies (AUD, CNY, HKD, INR, IDR, JPY, KRW, MYR, NZD, PHP, SGD, TWD, and THB) against USD over a period of fourteen years (from 2nd January 2001 to...

Corruption defined as the misuse of public power for personal gains is a forefront issue around the world, especially in developing countries. This paper mainly assumes that corruption has negative effects on government revenues both in the short-run and the long-run. In order to test this...
